Hello,
I'd like to try to get to the bottom of this, since the issue has
continued, and it would be great to be able to use fRMA with the MBNI
CDFs.
I can try it on a Linux system since I didn't do that yet, but do you
have any other suggestions for trying to troubleshoot? I certainly
hope it's not an issue between 32 and 64 bit versions of R.
Thanks,
Adam Cornwell

Adam,
It seems to work fine for me (see below). Not sure what the issue is;
the only difference I see between our sessionInfo() is 64bit vs 32bit.
I am a few versions behind on the alternative CDFs -- currently all
the frmavecs use entrezg v16. But you seem to have figured this out
based on your sessionInfo().
As to your bigger question, using the alternative CDFs doesn't violate
any assumptions in fRMA, and a fair number of other people use them
together. I do have to make a separate set of frozen parameter vectors
for these CDFs and since they are updated fairly regularly, I am often
a version or two behind. But that's not a reason to not use them (and
bug me when I fall too far behind).

3.0.2 and the newest version of BioC. I'm trying to use fRMA with some
U133+ 2.0 arrays, and getting errors with custom CDFs. It works fine
with the stock CDFs. I've tried both robust_weighted_average and
random_effect for summarization. I've also tried BrainArray CDF
versions from 15 to 18 (all EntrezGene). The error is different
between using random_effect and robust_weighted_average.

would you actually recommend using the BrainArray CDFs with fRMA? It
seems like the combination of probe weighting based on data, and probe
selection based on re-annotation would produce some nice results- if
using the custom CDFs doesn't break any assumptions made in fRMA.
